I have a 9'2 longboard with a thruster set-up. I would like to be able to change the set-up to a single fin but I cant as the longboard fins only come in the box type conector. Anyone have any ideas on how to get around the problem?
How much hassle is it to change the centre fin plugs to a fin box?
Or, how much time, money is it to get the shop to do it

Thanks
